Answer:
The equation of the line would be y = -15/24x + 6
Step-by-step explanation:
In order to find the equation of the line, you need to start by using the slope formula with the points given. This will give you the slope.
m(slope) = (y2 - y1)/(x2 - x1)
m = (11 - 7/2)/(-8 - 4)
m = (15/2)/-12
m = 15/-24
m = -15/24
Now that we have the slope, we can use that and either point to find the equation in point-slope form.
y - y1 = m(x - x1)
y - 11 = -15/24(x + 8)
y - 11 = -15/24x - 5
y = -15/24x + 6
Answer:
11
Step-by-step explanation:
f(x) = x^2 - 3x + 1
f(-2) = (-2)^(2)-3(-2)+1
f(-2) = 4 + 6 + 1
f(-2) = 11
Just substiute -2 for x and sove.
There was 32 total pupils and 2 obtained a level 5, so you subtract 2 from 32 and get 30. Then you divide 30 by 5 because to give you the the number of students which got a level 4 which is 6. 6+2=8 32-8=24
Level 4; 6pupils
Level 3; 24
Level 5:2
Step-by-step explanation: x+(x+2)+(x+4)+(x+6)+(x+8)+(x+10)=126
6x+30=126
6x=96
X=16
Since x is the first number , x+6 is the fourth even number .
Thus, the fourth number in the sequence is 22
Answer:
Equation of line is:
Step-by-step explanation:
Let equation of line be y=mx+c
where m is the slope of line and c is the y-intercept
Line passes through (2, -1/2) and has a slope of 3
i.e. (x,y)=(2, -1/2) and m=3
i.e.
So, equation of line is:
